Beach was created in February when the foundation entered a joint venture with Birmingham, Ala.-based Surgical Care Affiliates LLC. The foundation is the medical group division of the $2 billion nonprofit MemorialCare Health System, which now is based in Fountain Valley but plans to move to Costa Mesa later this year. The foundation also is expected to make the move as MemorialCare consolidates its administrative operations in a newly bought headquarters building in Costa Mesa.
